Module use precautions.

When using the WIFI module of Uascent Technology, a certain tolerance should be reserved for the output current of the power supply. It is recommended that the output current of the power supply be ≥ 500mA, and a suitable power supply IC packaging should be selected. When using LDO power, attention should be paid to the issue of thermal, and when using DC-DC power, attention should be paid to the issue of overshoot at the moment of power on.

Antenna Information.

Antenna type.

This module antenna type is PCB on-board antenna with antenna gain of -1.3dBi (MAX )

Module layout considerations.
The UAM083-A0 module shall be welded to the PCB board. In order to obtain the best RF performance. Under the PCB on-board antenna, there should be no copper laying, device and wiring. During PCB design, the corresponding area should be cleared. As shown in the following figure.

Environmental Requirements.

Recommended Reflow Profile.
Referred to IPC/JEDEC standard.
Peak Temperature : <250°C
Number of Times : ≤2 times

8.2 Note.
Note:Take and use the module, please insure the electrostatic protective measures.

1. Reflow soldering temperature should be according to the customer the main size of the products, such as the temperature set at 250 + 5 ℃ for the MID motherboard. About the module packaging, storage and use of matters needing attention are as follows:
2.  The module of the reel and storage life of vacuum packing: 1). Shelf life: 8 months, storage environment conditions: temperature in: < 40 ℃, relative humidity: < 90% r.h.
3. The module vacuum packing once opened, time limit of the assembly:

Card:

1.  check the humidity display value should be less than 30% (in blue), such as: 30% ~ 40% (pink), or greater than 40% (red) the module have been moisture absorption.
2. factory environmental temperature humidity control: ≦ -30 ℃, ≦ 60% r.h..
3.  Once opened, the workshop the preservation of life for 168 hours.
4. Once opened, such as when not used up within 168 hours:
5. The module must be again to remove the module moisture absorption.
6.  The baking temperature: 125 ℃, 8 hours.
7.  After baking, put the right amount of desiccant to seal packages.

Humidity sensitive control.

Package.

Packaging Detail.
The module and the humidity indicator card are placed together in vacuum anti- static packaging, separated by a certain amount of paper, and neatly placed in the packaging box.The packaging must have reliable moisture-proof and anti- collision measures.
